Biological membranes are complex structures that separate the interior of cells or organelles from their external environment. These membranes are composed of a variety of lipids, proteins, and other molecules that help regulate the flow of substances in and out of the cell. They also play important roles in cell signaling, adhesion, and energy production. Research in the field of biological membranes focuses on understanding the structure, function, and dynamics of these membranes, as well as how they are involved in various cellular processes and diseases. This research often involves using a combination of biochemical, biophysical, and imaging techniques to study membrane proteins, lipid composition, membrane trafficking, and other aspects of membrane biology. Ultimately, this research aims to provide insights into how biological membranes contribute to the overall function of cells and organisms.
